摘要

摘要: 通过野外调查与室内分析相结合的方法,对丘陵山地茶园土壤团聚体及其碳含量分布特征进行研究。结果表明:茶园土壤0~20 cm以>5 mm团聚体含量最高,占20.59%,20~40 cm土层土壤团聚体以5 mm粒径土壤团聚体有机碳含量最高,团聚体基本呈现粒径增大,有机碳含量增加的规律。茶园在0~20 cm土层>5 mm粒径土壤团聚体有机碳储量及其分配比例最大,0.25~0.5 mm团聚体含量最少,而20~40 cm土层以0.25~0.5 mm团聚体土壤有机碳储量及其分配比例最大,>5 mm团聚体的比例最小。

Abstract: Distribution of soil aggregates and organic carbon were analyzed in hill tea plantation by the methods of field investigation and laboratory analysis. The result indicated that the soil granule structure of tea plantation was dominated by >5 mm aggregate for 0-20cm soil layers, accounting for 20.59%, the soil granule structure of tea plantation was dominated by 5 mm were the highest for both 0-20 cm and 20-40 cm soil layers, and the content of organic carbon increased with increment of aggregate size. The reserve and distribution of the ratio of organic carbon in >5 mm aggregate in 0-20 cm were the highest and in 0.25-0.5 mm were the lowest. On the contrary, the reserve and distribution of the ratio of organic carbon in 0.25-0.5 mm aggregate in 20-40 cm were the highest and in >5 mm were the lowest.
